This is a large plate of fossil seed ferns from the Coal Age deposits near St. Clair, Pennsylvania. It is very hard to get a slab this nice from this site. The entire plate is covered with large seed fern fronds and branches. The seed ferns are preserved as a thin film of white pyrophyllite on black shale. There are several different types of seed ferns represented on the plate, and even the horsetail Sphenophyllum is represented. The fossil plants have excellent color and contrast and exhibit superb detail. There are also many seed ferns on the reverse side of the plate. This is a museum quality plate of Pennsylvanian plants from a classic location.
